I've got stock resized rods with a set of ARP connecting rod bolts / nuts. Their directions indicate using their own Ultra-Torque fastener assembly lubricant. Any comments on using this vs the old school thought of loctite that was used on rebuilds with stock bolts / nuts?

The current train of thought as I get it is to focus on applying the proper bolt stretch and torque by allowing the nut to spin more freely with lubricant rather than using loctite which causes the nut to lock into place, but possibly with the incorrect torque and bolt stretch. I don't see that happening unless you waited too long and the loctite dried, but that's only my novice opinion. I can see that lubricant might help the bolts to be used for a couple of more rebuilds.

What do you engine builder gurus say?
